Re: [PD] [OT] next Linux kernel and Hammerfall cards

re: [PD] Frequency Analysis.... // libmpeg3

hi Fares, i\'m using fft with tabread and tabwrite to control the video via audio analysis. I\'m attaching a patch which i\'m using, maybe you\'ll find it helpfull.. It\'s certainly not the best way how to do it, but it works :) /////////// To the list: is there a way how to play back video in mpeg3 format, and to control the decoder? libmpeg3 seems to be the best choice - is it possible to compile (& use) under WinXP? I just want to use mpg video in my performances and to play with the decoding (make it corrupt, or just use the algorythm in any weird way) .. Has been somebody doing it yet ?(or just working with lbmpeg3 ?) thx gnd/ ________ Zabava, zabava, zabava - www.zabava.sme.sk

USB GAMEPAD
by shreeswifty 19 Nov '03

19 Nov '03

Hi Folks I am trying to use a Gravis GamePad with PD. I am interested in using it with granuloop but it seems to NOT like it. If i simply load the joystick.pd file from Joe Sarlos site, i get it to load, Joystick 1 two axes, 10 buttons. but as soon as i try to load it with granuloop it says scan:: no such object. I am not sure if the gamepad is supported or not this is on WInXp cheers~ Patrick Pagano, B.S. Research And Development Assistant Digital Worlds Institute University Of Florida (352) 294-2070

reading FFT blocks in a wrong order
by julien.breval＠tremplin-utc.net 19 Nov '03

19 Nov '03

hello again, something about spectral domain transforms in my patches, I use [rfft~] as forward FFT if there is a [block~ 128 2] object in the subpatch, the outputs of [rfft~] are two arrays of size 128 (amplitude spectrum and phase spectrum) ; [rfft~] outputs these arrays as 2 signals (circular reading of the arrays ala [tabsend~] / wavetable) is it possible to have a control on the reading index of these arrays ? For example, I would like to read the arrays (phase and amplitude spectra) with a [line~], a [phasor~] or any other signal but it seems to be an automatic process thanks --

(don't > forget to turn the audio-engine on...) you're right, using [pix_videoNEW], [pix_pix2sig~] and [pix_sig2pix~] I see the captured image !!
